    (RF) transceiver and Passive Infrared (PIR) motion detector. The e528 interfaces with all common HVAC unit voltage configurations (24 volt to 277 volt). The e528 can be installed in a wired or wireless INNCOM guestroom control system, which makes installation feasible and affordable in either new construction or retrofit installations.

    E528 Product Guide Mounting The e528 is usually mounted on a standard double-gang (4 x 4) junction box. If mounted on a single-gang box, the left side (display side) of the e528 overlaps the wall area to the left of the junction box. A low-voltage mounting plate, mud ring, or low-voltage caddy may be used for mounting 24 volt applications.

    * “3G,” and “4G” are internal INNCOM product designations used for convenience to differentiate individual hardware configurations. No difference in device capability or effectiveness is implied. Due to end-of-life for certain 3G components, the e528.4G is now the standard INNCOM install, but 3G installations are still supported.
